Your first point "Big Problem 1: The typical American dwelling is broken up into too many rooms." is exactly what I have found moving into my first house a few months ago. There are many rooms, but the space would be so much nicer if they could be consolidated into larger mixed use spaces. The technological advances of TVs and computer monitors make displays fit in so much nicer than in the past. Not to mention reducing the need for furniture duplicates. I suppose needs are different for those with kids who require a sound barrier, but I'd personally like a 1 or 2 room home with tons of natural light.
